- the number of messages received in response to each sending of a test command corresponds to the current number N′x of electronic detonators 10 associated with this category of delay Cx.
- the current number N′x of electronic detonators 10 associated with each category of delay Cx also makes it possible to alternately determine, by calculation of the sum, the current number N′ of electronic detonators connected to the firing device 30.
- This information can thus be transmitted directly from one or more electronic detonators 10 to the firing device 30 and avoids any transfer of information by the mobile test device 20 or any other information medium.
- a comparison step S56 is implemented by the microprocessor 33 of the firing device 30.
- the current number N′ of electronic detonators 10 connected to the firing device 30 is compared with the set of values representative of the total number N of electronic detonators connected to the mobile test device 20 at the time of installation of electronic detonators 10.
- the current number N′ is calculated from the number of messages received at the reception step S52.
- the current number N′ is compared with the total number N of electronic detonators 10 or with the sum of the number Nx of electronic detonators 10 associated with each category of delay Cx.
- N' N WHERE where n is the number of delay categories of the set predefined at the time of installation at the face of the electronic detonators.

- the programming of the predefined delay associated with each electronic detonator 10 can be implemented by the firing device 30.
- the firing method comprises a step S58 of selecting an association model T as illustrated in FIG. 3, associating for each category of delay Cx a predefined delay according to a predetermined firing plan.
- the selection of the association model T can be implemented from association models stored in the programmable memory 34 of the firing device 30.
